APPARATUS FOR BURNING HYDROCARBON OILS WITH BLUE FLAME.

SPECIFICATION forming part of Letters Patent No. 603,072, dated April 26, 1898. Application iiled September 22, 1897. $erial No. 652,670. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRITZ ALTMANN, a subject of the King of Prussia, German Emperor, residing at Berlin, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Apparatus for Burning Hydrocarbon Oils with Blue Flame, of which the following is a specification.

This invention relates to certain improvements in apparatus for burning hydrocarbon vapors with a blue heating-flame.

In devices of this class, in which a mixture of hydrocarbon vapors and steam is employed for feeding the flame, the construction of those spaces in which the vaporization namely, the formation of vapor of the two substances that are mixed together-takes place is of special importance, inasmuch as in the constructions heretofore used,and espe- -cial1y where steam is carried through a too long system of pipes, a condensation of the vaporstakes place, which has the result that the flame obtained from such mixture cannot be used for heating purposes.

My invention relates to an apparatus for burning a mixture of vapors obtained from hydrocarbon liquid and water in such a manner that a blue and effective heating-flame is obtained and the stated objections thereby avoided.

In the accompanying drawings two diiferent forms of my apparatus are shown.

Figure 1 shows a vertical central section through one form of apparatus; Fig. 2, a horizontal section on line 00 00, Fig. 1; Fig. 3, a vertical transverse section showing a modified form of myapparatus; and Fig. 4, a horizontal section on line y y, Fig. 3.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, a represents a chamber or receptacle for the hydrocarbon 1iquid,such as petroleum b,the receptacle for water. Both liquids are raised by means of wicks, as shown in Figs. 1 and 2, from the receptacles a and b into the retorts c and d,which are supported by tubes a I), through which the wicks are led from the receptacles to their retorts. The retorts 0 cl are connected at their upper ends by a mixing-chamber e. In other words, they are divided by a partition 19 of less height than the chambers. The heating of the retorts is produced by the flame of a gas-burner f. The vapors of the hydrocarbon liquid are mixed with the steam obtained from the water in the mixing-chamher 6 and conducted from the latter to the burner g.

In the apparatus shown in Figs. 3 and 4 the liquids are conducted from the receptacles a b to the retorts c d, into which the liquids are raised by means of hydrostatic pressure. The retorts c d in this case are made in the form of curved tubes that are connected with the bottom of the receptacles a b. The vapors and steam are conducted to the mixing-chamber e, from which they are conducted to the burner. In both forms of apparatus the retorts are formed of two independent receptacles, so that it is obvious the retorts can be formed in one structure and separated by a suitable partition.

In the construction shown in Figs. 3 and 4, in which the liquids are conducted byhydrostatic pressure to the retorts, it may be advisable to introduce between the receptacles a b and the retorts c Wintermediate chambers for the purpose of preventing any transmission of heat to the receptacles a b and also for keeping up the regular supply of liquid to the retorts.

Both modified constructions show two separate receptacles for the liquids to be vaporized, which are connected with separate retorts that are again connected by a mixingchamber. Both of the retorts being open at their upper ends, the hydrocarbon vapors formed in one retort and the steam generated in the other retort can be readily mixed in the mixing-chamber and conducted from the same to the burner. By this arrangement the following advantages are obtained:

First. No intermixing of the liquids takes place in the retorts, so that a perfectly reliable evaporation and mingling of the vapors in the mixing-chamber, and thereby a steady flame, are obtained.

Second. As the steam-conduit is comparatively short, no condensation of steam takes place.

Third. The intermingling of the vapors obtained from the hydrocarbon liquid and the steam obtained from the water is a very effective one.

Fourth. The utilization of the flame for heating the retort is obtained in a very simple manner, inasmuch as the flame heats both the retorts at the same time Without requiring separate flames for each retort, so that by raising or lowering the heating-flame below the retorts the useful effect of the flame under the retorts can be easily maintained.

Fifth. By the arrangement of the retorts in close proximity to each other and in connection with the intermixing-chamber above the same the intermingled vapors are heated up before they pass off to the flame.

For producing the intimate intermingling of the vapors additional appliances for this purpose may be employed such as screens, spirals, glass-wool, asbestos, and the like.

My improved apparatus is made and intended for the illumination of incandescent mantles, and the functioning of the same is readily understood from the foregoing description. The liquids employednamely, the hydrocarbon liquid and water-are in separate receptacles, from which they are conducted by capillary suction or by hydrostatic pressure to the retorts, in which they are changed into a gaseous state by the heat of a special heating-flame. From the retorts the hydrocarbon vapors and the steam are conducted to a mixing-chamber which is connected with both retorts and in which they are mingled, and from the mixing-chamber they are conducted to the burner, where the above said chambers and retorts, and a source of heat arranged below and intermediate of said retort, whereby the retorts are heated so that the vapors and steam produced in the same are commingled in the mixing-chamber and conducted from the same to the burner, substantially as set forth.

2. An apparatus for burning liquid hydrocarbons With a blue flame, the same consisting of two separate chambers, one being an oil-chamber and the other a water-chamber placed in close proximity and constructed to provide aeentral space between them, separate retorts connected with said chambers, a partition separating the retorts, a mixing chamber above the upper ends of the retorts, a burner above the mixing-chamber, and a source of heat for heating the retorts, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.
